Ash removal device of external gasification furnace

Abstract

The utility model discloses an external ash removal device of a gasification furnace, which relates to the technical field of ash removal of gasification furnaces and comprises a furnace body shell, a cooking bench is arranged at the top end of the furnace body shell, a combustion cavity, an ash falling cavity, a heating cavity and a channel are arranged in the furnace body shell, and a smoke exhaust pipe is fixedly connected to the side wall of the furnace body shell. A bottom pad and a filter screen are detachably mounted on the inner side of the smoke exhaust pipe through a mounting assembly; and a placement frame and a linkage assembly are arranged on the inner side of the heating cavity. According to the ash removal device of the external gasification furnace, the bottom pad and the filter screen are arranged on the inner side of the smoke exhaust pipe, so that ash deposited at the bent position of the pipe body can be received, dust can be filtered, it is guaranteed that exhausted gas cannot pollute the environment, and the heating cavity is internally provided with the placement frame and the linkage assembly, so that the heating efficiency is improved. The effect that the placing frame can be automatically moved out of the heating cavity along with opening of the sliding door can be achieved, and therefore the problem that hands are scalded when food is placed in is avoided.
